Is This an iPhone 5 Prototype Switching GPUs? [Video]

We were sent this video anonymously earlier this evening. The tipster says it shows the iPhone 5.

Watch as the user goes into System Settings. They select a special “Developers” tab, which then allows them to switch graphics processors.

The “Developers” tab suggests it’s a special prototype provided to partners to test the graphics performance…

There was a rumor in January that the iPhone 5 would have a dual core SGX543 GPU. The preference pane shows switching between SGX535 and SGX545 — a pair of graphics processors made by Imagination Technologies.

The GX535 is currently used in the iPhone 4. The iPad 2 uses the PowerVR SGX 543MP2, which is a screamer.

The other GPU in the video, the SGX545, was announced in January 2010. It’s a high-definition GPU, optimized for 3D. The specs say it delivers 40 million polygons per second at 200MHz. Apple is a part owner in the Imagination Technologies.

This could be fake, however. Someone may have created a fake “Developer” application that would add a phony tab to the Settings menu.

But if the video is genuine, the iPhone 5 looks just like the iPhone 4…
